Delete None values from Python dict

Question

Newbie to Python, so this may seem silly.

I have two dicts:

default = {\'a\': \'alpha\', \'b\': \'beta\', \'g\': \'Gamma\'}
user = {\'a\': \'NewAlpha\',          


        

Answer 1

With the update() method, and some generator expression:

D.update((k, v) for k, v in user.iteritems() if v is not None)
